A question about the message displayed when running dc_shell 2024.09.

joshua2784920

When running dc_shell, the following message appears:


Info: [VCS_SAVE_RESTORE_INFO] ASLR (Address Space Layout Randomization) is detected on the machine.
To enable $save functionality, ASLR will be switched off and simv re-executed.
Please use '-no_save' simv switch to avoid this.


Could you explain what this message means?
